Definitions

  • the present invention relates to a foldable head for a maize picking machine.
  • the problem of said abnormal and larger than usual occupancy can be solved in two ways: the first one provides for properly escorting and signalling such abnormal size; a second known way consists in building the heads as foldable heads, such as to allow a normal occupancy of the roadway during the transportation thereof.
  • a head for a maize picking machine two essential requirements are to be considered in a design allowing for the folding up of the head and the restoring to the original size thereof in the field that is to be harvested: the pick up screw and the plurality of chains for pulling the cobs from the ground to said screw that are provided in a number of one for each tooth.
  • the means for restoring the head to the extended configuration is therefore to be quite accurate, easy to be handled and ensuring an accurate coupling between the different members to prevent umbalances therebetween.
  • a typical example of coupling means for said foldable members consists in the use of a forked "joint" comprising at least two members provided with facing projections, positioned in such a way as to be introduced into each other upon the opening and the fixing of the head, so as to create a constraint adapted to allow the synchronous movement of the members.
  • the object of the present invention is to overcome the above mentioned inconveniences by creating a practical and effective joint both for the screw and for the shaft driving the chains.
  • the foldable head for a maize picking machine is a conventional head that is rendered foldable through the use of fluid pressure means, such as hydraulic cylinders moving along one direction and the opposite one the head movable side portions, characterized in that the clutch engagement means provided for the screw shaft comprises at least a clutch flange fastened to the movable portion of the screw shaft, that can clutch another similar flange fastened to the fixed portion of the screw shaft, said clutch engagement taking place thanks to axial pins orthogonal to the surface of one flange and regularly spaced thereon fitting into as many corresponding axial cavities provided on the surface of the other flange which is supported by suitable elastic means that are coaxially located with respect to the fixed portion of said shaft, and in that also the clutch engagement means provided for the shaft driving the chains moving over the teeth comprises at least one clutch flange fastened to the movable portion of the shaft driving the chains that can clutch another similar flange fastened to the fixed portion of the chains shaft, said clutch engagement taking place thanks to axial pins orthogonal to the
  • a further relevant feature of the present invention resides in that according to a preferred embodiment the joint by means of the coupling of flanges with axial pins for the screw shaft is only provided at one side of said screw, at the other side said shaft being controlled through conventional means, such as a toothed gear and a chain, whereas the joint by means of the coupling of flanges with axial pins for the shaft driving the chains is provided at both sides of said shaft.
  • the number of axial pins provided for the coupling flange of the screw shaft is four, whereas the number of the axial pins provided for the coupling flange of the shaft driving the chains is three.
  • the foldable head for a maize picker is a conventional head 1 that has been rendered foldable thanks to fluid pressure means, such as a hydraulic cylinder 3 that moves along one direction and the opposed one the movable side parts 5 of the head in such a way as to fold them up and get a head having a reduced width adapted to be easily transported on a road from the store to the fields and viceversa.
  • fluid pressure means such as a hydraulic cylinder 3 that moves along one direction and the opposed one the movable side parts 5 of the head in such a way as to fold them up and get a head having a reduced width adapted to be easily transported on a road from the store to the fields and viceversa.
  • the clutch engagement means provided for stiffening the screw shaft after the removable portions 7 thereof and the fixed portion 9 have been joined together, comprises a clutch or coupling flange 11 fastened to the movable portion 7 of the screw shaft, adapted to clutch a similar flange 13, fastened to the fixed portion 9 of said shaft. Said clutch engagement is carried out through axial pins 15 that are orthogonal to the surface 17 of one flange fitting into as many corresponding regularly spaced cavities 19 provided on the surface 21 of the other flange which is supported by suitable elastic means 23 coaxial with the shaft 9.
  • the clutch engagement means provided for stiffening the shaft which drives the chains 25 moving over the teeth 27 comprises at least a clutch flange 29 fastened to the movable portion 31 of the shaft driving the chains, adapted to clutch another similar flange 33 fastened to the fixed portion 35 of said shaft.
  • Said clutch engagement takes place through the fitting of axial pins 37, orthogonal to the surface 39 of one flange and regularly spaced thereon, into as many cavities 43 of the other flange, in case also this latter being supported by suitable elastic means 44.
  • a dedicated safety device made up by a rod 45 that can be slidably inserted into a slotted seat 47 provided in the lower portion 49 of the head, in correspondence with the walls of the teeth, which is fastended to the fixed portion and can be introduced into a suitable slot 51 provided in the movable portion thereof; said rod 45 being directly actuated by the user through a proper linkage 53, 55 connecting said rod with the control device 57.
  • the joint by means of the coupling of flanges 11, 13 with axial pins for the screw shaft is only provided at one side of said screw, at the other side said shaft 7 being controlled through conventional means, e. g. see the toothed gear 59 and the chain 61, whereas the joint by means of the coupling of flanges 29, 33 with axial pins for the shaft driving the chains is provided at both sides of said shaft.
  • the number of axial pins 15 provided for the coupling flanges 11, 13 of the screw shaft is four, whereas the number of the axial pins 37 provided for the coupling flanges of the shaft driving the chains is three.
